This paper deals with the dynaumic response behavior of ring-like hexagonal floating structure supported by columns in regular waves, as a part of basic studies on floating artificial islands. The dynamic response behavior of a 1,000m-class structure under trial design in regular waves is numerically obtained by using framework model on an elastic foundation. Effect of the bending rigidity on the frequency response amplitude of the structure are also investigated by numerical calculations for various values of the bending rigidity. It is found from calculation results that the effect of the bending rigidity on the response amplitude of the bending moment is remarkable. On the other hand, the effect of the bending rigidity on the response amplitude of the displacement aud torsional moment is comparatively little.
